MACHINE FOR FEEDING CIRCULAR BIETET-CAPS' .AND THE LIKE.

To all 'whom z' may concern.'

Be it known that I, ARTHUR R. HAVENER, a citizen of the United States, residing at lVayland, in the .county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Machines for Feeding Circular Rivet-Caps :and the like, of which the following is .aspecificatiorr This invention relates to lmachines for feeding and positioning disk shaped articles such as rivet caps and the like.

The object of the invention is to provide a simple and efficient means for feeding rivet caps which shall elfect the rolling of said ca s upon their peripheries rather than the slicing of the caps upon their faces,'.es pecially along such portions of a raceway cas may be slightly inclined to the horizontal,

whereby the possibility of the clogging of said raceway by failure of the caps to pass along the same is reduced' to a minimum, and at the same time the speed at which the caps will move along/said raceway isV increased..

The invention consists, particularly, in the formation and arrangement of the different parts .constituting the raceway by which the rivet .caps are fed from a hopper to the rivet and cap setting instrumentalities.

The invention further consists in so combining the raceway with the reciprocatory feed slide that the rivet caps are changed in position, from a vertical position in which they roll upon their edges to .a horizontal position in which .they are fed by said slide.

The invention further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.l

In .the specification .and drawings I have described and illustrated my invention as. embodied in a machine of the type disclosedv in U. S. Patent No. 1,276,652 issuedto Ine August 20., 191.8.

Referring to the drawings: Figure 1 is a lef-t hand side'elevation of a rivet and cap setting `machine with features embodying this invention shown in connection therewith, parts .of said machine bein-g 'broken away to .save space in theA ence may drawing.

Like numerals refer to like parts throughout the several views of the drawings.,

In the drawings, 1 is the frame of a rivet and cap setting machine, and extending forwardlyi from the frame 1 is an arm 2 bear-r ing at its outer end a work-support.- An

anvil 4 is arranged to reciprocate vertically in the outer portion of said arm in copera-Y tion with a rivet driver 5 suitably arranged to be reciprocated in the frame 1 above said anvil by a pivoted lever 6 adapted to be.

operated by a crank 7 formed upon the driving shaft 8 of the machine, said crank 7 being connected withsaid lever by a link 9.

The anvil 4 is reciprocated at the proper time in the operation of the machine by a lever 10 pivoted at 11 in the arm 2 .and `carrying a roll 12. i

The roll 12 is maintained in operative engagement, by a spring 1.3, with .a reciprocatory cam slide 14 mounted in the arm 2 and the adjacent portion of the fra-me 1. A lever 15 operatively connected with the link 9 and pivoted at 16.0n said frame is arranged to impart a positive movement to said Islide 14 in one direction to raise the anvil 4 and to yieldingly movesaid slide in the opposite direction by means of a spring slide.

- strumentalities of the machine.

vThe present invention pertains particularly to the instrumentalities for transferring the rivet caps `from said hopper to said setting instrumentalities and consists of a raceway 19 formed in two `parts. 20

' and 21.

The part 20, which is inclined, has oppositely disposed grooves 22 and 23 formed longitudinally thereof for receiving opposite edges of the caps. The upper end of said raceway is attached to the hopper 18 with the grooves 22 and 23 disposed .so as to receive the caps from the hopper fiatwise,

but intermediate of its ends said raceway is twisted so that the caps passing down the same will be turned from iatwise positions to positions on edge whereby said caps will roll rather than slide along said raceway. At the lower end of the inclined portion 2O of said raceway is a substantially straight section 24. This section consists of two parallel plates 25 and 26Varranged one above the other and provided with oppositely disposed grooves'27 and 28, forming, continuations of the grooves 22 and 23, said grooves being arrangedl to receive the edges of the caps, as shown at 29, 29, Figs. 1 and 3, and

maintain said caps in substantially verticali p positions.

The lower strip 26 of said straight raceway section is rigidly secured to the yupper surface of thearm 2 and the upper section 25 thereof is pivotally mountedrelatively to said section 26 so that Vthe same may be swung upwardly and permit access to the caps 29 in the portion of the raceway formed by said sections.

In carrying out this feature of the invention the plate 25 is `provided with ears 30 to receive a hinge pin 31 which is supported in ears 32 formed upon a plate 33 rigidly secured to theupper face of the arm 2 in abutting relation to the plate 26. A spring 34 is secured to the arm 2 by a screw 35 and projects over the plate 25 in yielding engagement therewith to maintain said .plate in its operative position relatively to the plate 26.

The inclined raceway 20 not only in'clines downwardly toward the arm 2 at an angle abutting portions of the plates 26 and 33 and adjacent to the terminals of the grooves 27 and 28 in said plates 25 and 26.

The pocket 35 is constructed to hold a cap either in a vertical or flatwise position and is for the purpose of permitting a cap to be turned from avertical to a flatwise or horizontal position when the same arrives at the lower end of the inclined raceway.

Leading from the pocket 35 toward the lower end 36 of the inclined part of said raceway are grooves 37 and 38 rconstructed and arranged to guide said caps iiatwise. The lower end 36 of said raceway abuts against the end of the horizontal portion 21 of said raceway which preferably embodies in its construction two parallelly disposedv plates 39 and 40 arranged in spaced relation to provide a slot 41 therebetween.

The inner opposed edges of the plates 39 and 40 are grooved at 42 and 43 to coincide with and form continuations of the grooves 37 and 38 for the edges of the caps. The horizontal raceway section terminates in pivoted fingers 44 and 45 pivotally secured by screws 46 to the upper face of said arm 2. The lingers 44 and 45 are also arranged in spaced relation similar to the plates 39 and 40 and the inner opposed edges of said fingers are grooved at 47 and 47', respectively, to form continuations of the grooves 42 and 43, said grooves 47 and 47 terminating in segmental circular shaped recesses 48 and 49 adapted to position the caps, which are advanced along the grooves formed in said horizontal raceway, centrally above the anvil 4 preparatory to the setting of a rivet therein.

Springs 50 and 51 are secured to opposite sides of said arm 2 and yieldingly engage the outer edges of the fingers 44 and 45 toY maintain said fingers in their normal positions, that is, with the inner edges thereof parallel, said springs permitting said fingers to separate and release said cap when the anvil is moved upwardly into engagement with said cap.

The cam slide 14 has a rectangular eX- tension 52 constructed and arranged to slide along a groove 53 formed 'in the upper face of the arm 2, and along the space 41 between the plates 39 and 40 and also between the flanges 44 and 45, thek edges of said plates and said fingers constituting guides for said extension. The lower abutting portions of the plates 26 and 33 are slotted at 54 and 55 to enable said extension to pass through the ionnlmt R5 accomplish this res-ult the fo-rward end 56 of said extension' lnormally moves from At this time the lowermost cap, as shown at 57, Figs. 3 and 4, in the inclined raceway section, will, owing tothe relation' of said raceway to said extension, rest in an inclined position against the side of said es tension which is highV enough to prevent said cap from falling over flat on its face, but upon the retraction of said extension to a point where the end 56 thereof is at the rear of the pocket 35, said lowermost cap 57 will naturally fall to a horizontal or flatwise position in said pocket 35, as indicated in Figs. 5 and 7, directly in front of the end 56 of said slide and with its edges alining with the slots 37 and 38 in the lower ends of the plates 2,6 and 33. Upon the forward movement of said slide the end 56 will engage the cap 57 and push the same along the grooves of the raceway 21, from the pocket 35 into the pocket formed by the recesses 48 and 49 thus placing said tap in a position to be moved upwardly and out of said recesses by the upward movement of the anvil 4 when the setting instrumentalities are brought into play to set a rivet in the work.

Immediately upon the ejectionV of the cap 57 from the pocket 35 by said extension the next cap in the column of caps in the raceway will be forced down by the other caps therein into an inclined position against said extension in readiness to be transferred from the inclined raceway to said horizontal raceway upon the next operation of said slide.

Having thus specifically described my invention, what I claim and desire by Letters Patent to secure is:

l. In a machine of the class described, the combination of a raceway formed in two parts, one of said parts being arranged to guide caps flatwise, the other of said parts being constructed and arranged to guide caps on edge, a slide adapted to move said Acaps along the first-named part of said raceway and means including said slide for transferring said caps one at a time from the positions on edge to their flatwise positions.
